tative propagation does not, however, appear to take place in 
this manner. From reasons unknown to me, the shoots in the 
tufts often die off without any special order being possibly 
demonstrable to exist with regard to this point; scattered among 
the fresh parts occur old, decaying shoots (Fig. 2). 
The flowers (Fig. 3) are terminal, and, according to the in- 
vestigations of Warmine and Linpman they are slightly protogynous. 
WARMING writes (1886), p. 35, “in recently expanded flowers, the

are still closed and although they open immediately after, they 
do not do so until they are moved somewhat away from the 
stigma. They always remain at the same height relative to the 
latter, and can touch it and shed pollen upon it, if the stamens 
are bent inwards in the flower, which I have often done by way 
of experiment. Consequently, as the open anthers are usually 
at some distance from the stigma, self-pollination can take
